THE DAILY RECORD (BALTIMORE) -- NIMBYs represent the biggest obstacle to providing affordable housing in urban areas. At least that’s the argument put forth in a blog post on The New West, the official blog of the Western Political Science Association. In his post, Jason McDaniel, an assistant professor of Political Science at San Francisco State University, examines how progressive movements have stifled development in liberal urban areas — particularly San Francisco. “Because of the populism at its core, the progressive ideological coalition sees the problem of housing as a crisis of displacement of existing tenants and disruption of existing neighborhoods, rather than a crisis of available housing that is affordable to all who want to live in San Francisco,” McDaniel writes.
